, Specification of Letters Patent No. 8,782, dated March 2, 1852.

To; all whom it may concern:

Beit known that I, GERARD SICKELS, of

Brooklyn, in the countyof Kings and State of New York, have invented a new and Improved Friction'Clutch; andI do hereby declare-that the following is a full, clear,and exact description of the construction and operation of the same, reference belng had tothe annexed drawings, making a part of 10 jFgure 1,is an external view of the clutch. F ig. 2, is a descriptive view, the several partsrof the clutch being detached. Fig. 3,

e 1 ja sfi'de jviiew of'the boxes which contain the segments. Fig. l, is a faceview of the boxes, showingthesegments, and the screw rods and nuts by which thesegments are Similar letters of reference indicate correspondingparts in each of the several figures,

The nature of my invention consists in a peculiar manner of operating two or more segments, by which operation the segments are madeto bind in a V-shaped collar or be freed from it as desiredj the binding of the segments in the collar causing motion to be transmittedto certain parts of machinery to which the clutch maybe properly applied or stopping the motion of said parts of machinery by freeing the segments from the collar; the segments are operated by means of levers having arms attached to them, the arms being also attached to boxes in which the segments are fitted or placed. The arms and levers are so arranged that when the segments are bound or pressed in the collar they will not relax or become free from the collar without the application of some extraneous force.

My invention further consists in the employment or use of the V collar and segments inclosed in the boxes and arranged in a manner which will be hereafter described, in combination, with the manner of arranging the levers and arms.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, Figs. 1, 2, and 3, represents a shaft.

B, Figs. 1, and 2, is a collar attached per manently to the shaft, and having a square flanch (a) at one end, the fianch forming right angles with the shaft; on two of the sides of this fianch are projections (19). One only is seen, see Fig. 2, the other pro- H jection being on thef 'opposite side. These projections form right angles with theface of the fianch (a) 'and'are consequently parallel with the shaft A, and collar B; on these projections are placed two levers (C). One

precisely similar but are placed on the prowithin the boxes are placed segmentsE, E, Figs. 8, and .4 a segmentin each box. The segments work freely inthe boxes and are adjusted within them by screw rods (it) see dotted linesFig. 4:, which are operated by nuts Itwil'lbeseen thatthe screw rods are attached to the outer sides of the segments and pass through to the outer ends of the boxes and that by turning the nuts (2') the segments may be brought nearer, or removed farther from the shaft, A. a

F is a collar having a V groove in it see Fig. 2. Thiscollar is placed loosely on the shaft A. The inner ends of the segments are also V shaped see Fig. 3, and fit in the V recess in the collar. The dotted llnes in Fig. 4, show the position of the collar. Now thebinding or the pressure of the segment around the collar gives motion to it, it being remembered that the collar F, is placed loosely on the shaft and that the segments and boxes move with the shaft at all times whether the segments bind in the collar or not. This being understood it now remains to be shown how the segments are operated so that they can be .made to bind in the collar or be relieved from it, and also when the segments do bind in the collar, how they are prevented from reacting and becoming loose from the collar. This will be clearly seen by referring to Figs. 1, and 2. The arms (a?) (cZ) are attached by pivots (f) (f) to the boxes D, D, as has been before stated, and their opposite ends are attached to the lever C, by pivots (a) (6). Now it will be seen that the arms fipas seach other and are secured at opposite ends of the lever C. The consequence is that when the end or shank (j) of the lever C, is turned upward in the direction indiface of the flanch (a) see Figs. 1 and 2;

only is seen, Figs.1,and 2. The levers are jections (b) in a reverse manner as will be the lever C, work.

cated by the arrow 1, the arms (cl) (03) will be distended and the boxes D, D, and segments E, E, will be thrown or moved outward from the collar F, see Fig. 2, and that by the shank of the lever C, being moved downward the boxes and segments will be thrown or moved toward the collar. The levers C are operated by means of the sliding collar Gr, Figs. 1, and 2 which vibrates or moves over the stationary collar B. This collar G, has slots (70). One only is seen, in which pins (Z) in the shank j of The sliding collar G, has also a groove (m) around it in which the forked end of a lever may fit and by which the collar G, may be moved or vibrated, the moving or vibrating of the collar G, causing the levers C, to be turned, and

. certain distance.

are thrown toward the shaft.

the boxes and segments thrown from or toward the shaft. It will be understood that the segmentsrare so adjusted in the boxes by means of the screw rods (h) and nuts (2') as to bind in the collar when the boxes Now when the'segments are bound in the collar F, they will remain so unless the sliding, collar G, is moved, because the arms (d) (d) are attached to the levers G, in such a manner that the pivots (e) (e) or points of attachment are beyond the line of pressure X, X, and are prevented from going beyond a Consequently there can be no reaction,and the segments can not be released or freed from the V collar without the necessary extraneous force.

- Apulley wheel, or shaft, may be attached to the collar F. In the drawings Figs. 1 and 2, a pulley H, is represented. Thus power may be transmitted from the shaft A, to the pulley H, or vice versa, according as the vibrating slide G, is moved.

The clutch is not liable to get out of order,

is not expensive and in practice works Well. It requires no extraneous power to keep the segments bound in the V collar, as has been shown, after the connection is made.

I do not confine myself to any particular shape or form of levers C, or arms (d) It has been mentioned that the lever upon the opposite side of the flanch (a) was placed in a position reverse from the one shown. This is done in order to equalize the strain or pull upon the sliding collarG. The collar G", is prevented from turning on the collar B, by means of pins (0) (0) attached to the flanch (a) and pins fitting or working in recesses in the collar G, see dotted lines Fig. 2, or in other equivalent way. 7

Having thus described the nature and operation of my invention, what I claim as new and desire to secure by Letters Patent,

1. The arrangement of the levers C, and arms (d) (ol) for operating the segments E, E, substantially as shown and described, by which arrangement the segments are made to bind in the V collar F, or be relieved from it as desired, the segments when bound in the collar remaining in that state, the points or pivots (e) (6) having passed the line of pressure, unless acted upon by some extraneous force, as the moving of the vibrating slide G.

2. I claim in combination with the arrangement of levers and arms, the V collar F, and segments E, E, said segments being adjusted by screw rods (h) and nuts (2') as set forth.
